TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed October 5,1904. Serial No. 227,229.

To (all whom it may concern:

Be it known that I, Tnonas COUPON SMITH, a citizen of the United States, and a resident of Spokane, in the county of Spokane and State of \Vashington, have invented a new and useful Improvement in Type-'riting Machines, of which the following is a full, clear, and exact description.

The purpose of my invention is to provide a simple, effective, durable, and economic type-writing machine capable of being readily transported from place to place and operated without an inking ribbon and to provide adjustable pad-inking devices capable of supplying two or more colors of ink, to gcther with a wiping-section, any portion of which pads may be quickly brought into position for use.

Another purpose of the invention is to provide a practicable writing-machine that any person who can spell can use successfully and which is motor-controlled, so that the entire attention of the operator may be concentrated on the letter or character to be next written and brought under the pointer, no attention being necessary in any other direction.

A further purpose of the invention is to provide an interchangeable typecarrying plate forming a portion of a carriage, enabling a variety of styles of type to be employed on the one machine, and also to so construct the machine that it will be practicz lly noiseless in operation and so that there will be no complicated parts to adjust and repair and so that the machine in its entirety will occupy but a small space.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective View of the imview taken practicallyon the line 3 3 of Fig. 3. Fig. 1 IS a perspective View of a portion Fig. 2 is a trans- 1 plate of the carriage.

of the combined power and type-operating shaft and a perspective view of sectional or segmental threads which engage with the shaft and which are carried by a sleeve connected with the cover-plate of the carriage, a portion of which sleeve is shown by dotted lines. Fig. 5 is a view similar to that shown in Fig. a, the shaft, however, being in another position and the sleeve carrying the sectional or segmental threads being shown in section. Fig. 6 is a sectional plan view of the frame of the machine and parts carried directly thereby, together with means for automatically stopping the rotation of the power-shaft at the end of a line and manually stopping said shaft at any desired point in the length of a line. Fig. 7 is a transverse section through one end portion of the frame and a side elevation of the shifting device for the motor. Fig. Sis a transverse section taken practically on the line 8 8 of Fig. 7. Fig. 9 is a plan view of the bedplate for the carriage and the inking devices carried thereby, a part of the rotary portion of the carriage being shown by dotted lines. Fig. 10 is a bottom plan view of the said bed- Fig. 11 is an enlarged longitudinal section through one of the inking devices, taken practically on the line 11 11 of Fig. 9. Fig. 12 is a transverse section taken substantially on the line 12 12 of Fig. 11. Fig. 13 is an elevation of a part of one end of the frame and a section through the finger-knob of the line-spacing roller and its detent, and Fig. 1a is a perspective view of the detent shown in section in Fig. 13.

The frame of the machine, as illustrated, consists of a base 10, and on this base checkpieces 11 are secured, extending upwardly therefrom and located between the front and rear edges of the base. The said base at its rear right-hand portion has an extension (I, as is shown in Fig. 6, while the left-hand end portion (1' extends beyond the left-hand cheekpicce 11 from front to rear of the base, and at this portion of the base a chamber a is formed, in which a motor of any desired type may be placed,as the machine is to be motor-controlled.

A backboard 12 connects the rear end portions of the cheek-pieces 11, and the upper face of this backboard 12 constitutes a platen or a bed for that portion of the paper 13 adapted to receive an impression, as is illustrated in Fig. 2. Adjacent to the front face of the back or platen board 12 a feed-roller 14: is mounted to turn in the said cheek-pieces 11,

the said roller consisting ordinarily of a solid body 14, of wood or the like, and a covering of rubber or other material of a yielding character, and it may be here remarked that the upper edge of the back or platen board 12 may be likewise covered with an elastic material. The paper 13 passes over the roller 14, and as the paper is printed it is fed by the roller to the front of the frame, and the paper is held in suflicient frictional engagement with is operated whenever a line has been completed or whenever a sufficient number of words have been printed in a line and linespacing is desired. The line-spacing may be the ordinary full space, or the spacing known as close spacing may be secured by turn ing the knob more or less. To that end the said knob 16 is provided at its periphery with two series of depressions or recesses 17 and 18, the recesses or depressions in one series 0 having staggered relation to the recesses or depressions in the other series, and the recesses or depressions in one series are preferably made longer than those in the adjoining series, as is clearly shown in Fig. 6.

A detent 19 is employed in connection with the knob 16, the said detent being shown in Figs. 13 and 14. This detent consists of a spring-body which is secured at one end to the extension 0 at the right-hand rear portion of the base 10, and the opposite end of the said detent is forked, forming two parallel members 20 and 21, and these members extend beneath the knob 16. The ends of the members 20 and 21 of the detent 19 are upwardly bent, forming rounded projections 22, and these projections engage with the recessed peripheral portion of the said knob 16. If the line-spacing is to be close, the knob 16 is turned so that one of the projections 22 will click into one of the recesses of one series, the other projection of the detent being then upon a smooth space between the recesses of the opposing series; but if the spacing is to be the ordinary line-spacing the knob is still further turned until the second projection 22 enters a recess in the other series. Thus when the close spacing is to be effected the operator will know when the proper adjustment has been made by hearing but a single click, and if the ordinary spacing is to be given to the lines the operator will know when the adjustment has been made by hearing the second click. The detent 19 may have a single projection 22, adjustable to either series of depressions 17 and 18 in the knob 16.

A guide-shaft 23, polygonal in cross-section, is journaled at its right-hand end in a standard 24, extending up from the right-hand rear extension (0 of the base of the frame, as is shown in Figs. 2 and 6, and the other end of the said guide-shaft 23 is suitably journaled in a partition 25, located at the lefthand end portion of the base 10 of the frame, as is shown in Fig. 6. On this guide-shaft 23 the scale common to type-writing machines is produced, and the same scale is duplicated upon the upper face of the springplate 15.

Parallel with and in front of the guide-shaft 23 a combined power and operating shaft 26 is mounted to revolve, and the right-hand end of this shaft 26 is journaled in a standard 27 in front of the standard 24, heretofore referred to, and the standard 27 extends up from the rear right-hand end of the extension to of the base. The left-hand end of the combined power and operating shaft 26 is journaled in and carried through the partition 25 at the left of the frame and is provided witha gear 28, preferably a bevel-gear, to mesh with the driving-gear of the motor employed. The said shaft 26 is further provided witha series of pins 29, preferably arranged ten to the inch, and these pins extend practically from end to end of the shaft and are adapted in the rotation of the shaft to give sliding movement to a carriage A to be hereinafter described.

A supporting-bar 30 for the forward portion of the carriage A referred to extends from one cheek-piece 11 to the other near the forward ends of said cheek-pieces, and in the upper face of this supporting-bar 30 a longitudinal depression 31 is produced, in which depression a series of rack-teeth is formed, the teeth having their inclination in direction of the right-hand end of the machine, which is the direction of travel of the aforesaid carriage A.

The carriage A consists of a lower bed-plate B, an index-plate B, a type-carrying plate B and acover-plate B The bed-plate B is best illustrated in Figs. 9 and 10 and consists of a circular body-section 33, having a central opening 34, and acircular ball-race 35 is produced in the upper face of the said body 33, concentric with the opening 34, the said ballrace being adapted to receive balls or bearings 35, as is shown in Fig. 2. Horizontal arms 36 extend from opposite sides of the body 33 of the bed-plate B, and these arms have an outward and a rearward inclination.

Upwardly-extending flanges 37 are located at the sides of the arms 36, extending nearly to their outer ends, and at the extreme outer end portions of said arms 36 at each side standards 38 are erected. Each standard 38,

as shown in Fig. 11, is provided wit-h a shoulder 39 upon its inner or rear vertical edge. A short shaft 10 is journaled in opposing standards 38 of the arms 36, and on these shafts 10 a cam-lever11 is secured, which lever when carried downward and inward, as shown by positive lines in Fig. 11 and likewise in Fig. 9, is in locking position, and the said levers are in releasing position when carried upward and outward, as shown by dotted lines in Fig. 11.

A tray 12 is adapted to slide on each arm 36 between its side flanges 37, as is shown in Figs. 9 and 11, and this tray is provided with spurs 13 on its bottom portion to prevent the articles carried from slippin Each tray carries a number of pads, usually three, an outer pad 11, an inner pad 16, and an intermediate pad 15. The outer pads, for example, are saturated with one colorof ink and the inner pads with ink of another color, while the intermediate pads are preferably utilized as wiping-pads. Any one of these pads can be brought into action with relation to the type to be hereinafter described by simply shifting the position of the trays, and to that end each tray is provided with a handle at its outer end extending downward from the body, as is shown in Figs. 1, 10, and 11.

A center stud 18 is secured to the bed-plate B, being passed through the central opening 31', as is shown in Fig. 2, and this stud 18 at its lower end is illustrated as secured to ribs 51, located in a depression in the bottom of the body 33 of the said bed-plate, as is shown in Fig. 10, the said ribs 51 extending slightly over the said opening 31 in the bedplate. In the bottom of said stud 18 a frictionroller 19 is mounted, which travels upon the plain surface of the supporting-plate 30. The upper end 52 of the stud 18 is reduced and exteriorly threaded to receivea nut 53, which is preferably a thumb-nut. At the bottom portion of one arm 36 of the bed-plate B a gravity-pawl 51 is located, as is shown in Figs. 2 and 10, and this pawl is adapted to engage with the rack 32 on the supporting plate or bar 30, so as to prevent the carriage from accidentally moving backward, but not interfering with the advance movement of the carriage.

The index-plate B is of circular formation and is flat. The said index-plate B at what is its rear peripheral surface has a recess 51 produced therein, as is shown in Figs. 2 and 3. This recess extends nearly one-half the circumference of the said index-plate, as indicated by dotted lines in Fig. 3.

The type-carrying plate B is of spider-like formation, as is shown best in Fig. 3, and comprises a peripheral segmental section 55, a central inwardly-extending spider-arm 56, and two side spider-arms 57, which connect with the central spider-arm 56 and with the end portions of the segmental peripheral section 55. The segmental peripheral section 55 of the type-carrying plate B is located over the recess 51 in the index-plate B, as is shown in Figs. 2 and 3, and the center spider-arm 56 is more or less recessed to loosely receive the stud 18. The index-plate B is provided with recesses 58 in its upper face, into which recesses the spider-arms 56 and 57 of the typecarrying plate B are entered. so that the upper face of the type-carrying plate B is flush with the upper face of the index-plate B.

In order that the type-carrying plate B shall not accidentally leave the index-plate B, lugs 59 extend from the index-plate over the spider-arms 57 of said type-carrying plate B as is shown in Fig. 3, and a button 60, pivoted upon the index-plate B, is carried over the inwardly-extending central spider-arm 56. It will be observed that the type-carying plate B may be readily removed from the indexplate and another one substituted when desired.

At the outer edge of the peripheral member 55 of the type-carrying plate B a series of conical openings 61 are provided, narrowest at their bottom portions, the openings extending through the said member, as is shown in Fig. 2. These openings are arranged about as close together as are the pins 29 on the combined power and operating shaft 26, and the type 62 are formed upon rubber strips or elastic strips of any suitable material. Each type may be on a separate strip, or all of the type employed in connection with the plate B may be formed upon one strip. No matter, however, how the type are formed on their elastic strips a type is located below each of the openings 61, as is indicated in Fig. 2. The number of openings 61 and of type 62 corresponds to the number of large and small letters in the alphabet and the numberof punctuation-marks and characters ordinarily employed in literary work.

An index B is produced upon the front upper face of the index-plate B, and this index B" consists of letters, large and small, punctuation-marks, and characters, arranged in segmental rows, the letters or characters in the said rows bearing such relation as to read from the front central portion in opposite directions, as is clearly shown in Fig. 3. Each type of a letter, character, or designatingmark is diametrically opposite a corresponding letter, character, or designating-mark on the index B", the imaginary connecting-line being drawn through the center of the stud 18, and in order that the index-plate may be moved rapidly after a person has familiarized himself with the index on the plate aseriesof gage-marks 63 is produced on the plate inside of the inner row of characters, letters, and designating-marks, one gage-mark 63, which gage-marks are in the form of short lines, be-

ing provided for each letter, designatingmark, or character used in the make-up of the index.

At the central portion of the index the word Stop is produced, and immediately oppostrip is pressed downward there will be no impression. A rail 66 is attached, by means of lugs 64 and 65, to the front edge of the indexplate B, and on the lug 64: the abbreviation Caps is produced, and on the lug the words and abbreviation Figures and Char appear. Preferably in the arrangement of the index B the capital letters commence from the lug 6 L and read to the left in direction of the rear, and from the right-hand side of the lug 64 to a point beyond the right-hand side of the lug 65 are arranged the numerals, small letters, abbreviation-marks, and characters, as is clearly shown in Fig. 3.

The cover-plate B is more or less dished, having a convexed upper and a concaved under surface and is adapted for attachment to the outer ends of the arms 36, forming a portion of the inking mechanism.- The combined index and. type-carrying plates B and B revolve freely on the ball-bearings 35 between the bed-plate B and the cover-plate B and according to the position in which the trays 42, carrying the inking-pads are placed, will the type pass over one or the other of the pads carried by said trays. The manner of attaching the said cover-plate to the said arms 36 of the bed-plate B is by producing lugs 67 at the peripheral surface of the cover-plate, which lugs 67 rest upon the shoulders 39 on the standards 38, carried by said arms 36, and when this engagement is brought about the cam-levers 41 are carried down to their clamping position, (shown by positive lines in Fig. 11,) and as the cam-surfaces of the levers will then be below their pivot-points the said cam-surfaces of the levers will have firm bearing on the upper surfaces of the lugs 67, and thus firmly secure the cover-plate B in position. The coverplate B at its rear portion is practically straight and slightly raised and is provided near its sides with arms 68 and 69. These arms are continued rearward, being arched over the combined power and operating shaft 26, as is shown in Figs. 1 and 2, and terminate in sleeves 70, corresponding to the crosssectional shape of the guide-shaft 23, upon which shaft the said sleeves 7 0 are adapted to slide. The under faces of the bowed portions 68 of the arms 68 and 69 are provided with members 71, as is shown in Figs. 4: and 5, said members extending diagonally of the said arms. In fact the members 71 form a mutilated thread on each of the arms 68 and 69, and the pins 29 on the combined power and operating shaft 26 as the said shaft revolves pass between the members 71 of the said mutilated threads and cause the carriage A to be fed step by step from left to right of the frame.

An opening 72 is made in the front edge of the cover for the index-plate B and at the center of this opening 72 a pointer 73 is formed, extending in a forward direction, and the letter, numeral, character, or punctuation-mark that it is desired to print is brought by the rotation of the index plate B under this pointer, whereupon the corresponding type will be in position to be acted upon byasuitable plunger and through the medium of the teeth 29 on the shaft 26, which plunger and the means whereby it is operated will be shortly described.

A cross-bar 7 4 connects the arms 68 and 69 at their rear portions, and this bar 7 4 is provided with a pointer 75, which extends over the scale produced on the guide-shaft 23, as is shown in Fig. 1.

Horizontal lugs 76 are rearwardly projected from the rear end of the cover-plate B between the arms 68 and 69, as is shown in Fig. 1, and these lugs 76 support the mechanism for depressing the type as the type is brought in position for printing. This mechanism D consists of elbow-levers 77, suitably fulcrumed on the said lugs 76, and front and rear bars 78, connecting the ends of the said levers 7 7 together with a lower bar 79, extending from the lower central or angular portion of the one elbow-lever to the other. A spring 80 is coiled around this lower bar 7 9,'being attached at one end to the bar and at the opposite end to the cover-plate. This spring 80 serves to hold the elbow-levers in their upper or normal position. (Shown in Fig. 1.) In fact, the said levers and their connecting-bars form a cradle, which rocks on the said cover-plate, and the said printing mechanism is completed by the addition of a plunger 81, which extends down from preferably the central portion of the forward connecting-rod 78, as is shown in Fig. 2, and when a type is in position to print, as is shown in Fig. 2, one of the pins 29 on the shaft 26 will engage with the rear bar 78 of the said cradle and will rock the same downwardly and forwardly, thus forcing down the plunger 81, which will enter the opening 61 beneath it and engage with the type-strip 62 below the said opening, and will force the type on the strip to printing engagement with the paper 13. It may be here remarked that the supporting-bar 30 for the forward end of the carriage is provided with a more or less triangular bottom, as is shown in Fig. 2, so as to offer the least possible resistance to the forward feed of the paper.

As has been stated, the combined power and operating shaft 26 is rotated by gear connection with a motor of any suitable description, and the mechanism which is employed for throwing the motor into and out of gear with 'the said shaft 26 automatically and manually is as follows: The right-hand sleeve 70, con- I guide-shaft 23, will engage with the inner neeted with the carriage A at the upper portion of its right-hand end, is provided with a beveled surface 82, (best shown in Fig. 7,) and at the right-hand end of the guide-shaft 23 a pin 83 extends outwardly, preferably forwardly, from the said guide-shaft. The lever St is fulcrumed about centrally on the forward edge of the right-hand upright 2 L, as is shown in Figs. 7 and 8,and this lever is provided with a hook-shaped head 85, pivotally attached to the rear face of the said lever St at its upper end. Normally this curved head 85 of the lever 84 extends over a forward projection 86 from the aforesaid right-hand standard 2+t, as is shown in Fig. 7. A shifting rod 87 is pivotally attached to the lower end of this shifting lever 84: and the rod 87 extends along the rear portion of the base. as is shown in Fig. 6, and is pivotally connected with the under face of the peripheral surface of a wheel 88, which is mounted to turn on the base near its left-hand end, as is also shown in Fig. 6. A second shifting rod 89 is pivotally attached to the upper surface of said wheel 88 adjacent to the attachment of the shifting rod 87 with said wheel, and the shifting rod 89 is connected with the clutch or other mechanism employed on the motor for starting and stopping the same.

A spring 90 is attached to the wheel 88 and to the base 10 at a point forward of the wheel, and the spring 90 acts'to turn the wheel in a direction to draw the rod 87 in direction of the left-hand end of the base and carry the rod 89 in the same direction and disconnect the clutch on the motor to stop the same; but this action cannot take place until the curved head 85 of the lever 84: is released from the projection 86, as while said head 85 is in engagement with said projection 86 the rods 87 and 89 will have been drawn to the right sufficiently to bring the said clutch or its equivalent in such position as to cause the shaft 26 to revolve.

The revolution of the shaft 26 is automatically stopped by the beveled surface 82 of the righthand sleeve when the carriage has been carried to the right as far as possible, engaging with the inner end of the head 85, which end is beveled, lifting the hook 85 from off its keeper 86, whereupon the lever Set is free to assume the position shown by dotted lines in Fig. 7, so drawn by the action of the spring 90. and the driving connection between the motor and the shaft 26 is immediately stopped.

lien it is desired to write only a portion of a line and then stop to take the carriage back to its normal position, when the last letter on the line has been written the carriage is carried to the upright rearward position shown by dotted lines in Fig. 2, whereupon the guide-shaft 23 will berocked in arearward direction, and the pin 83, carried by the end of the curved head 85 of the lever 84 and lift said head from its keeper 86, whereupon the shaft 26 will be practically uncoupled from the motor. \Vhen it isagain desired to cause the motor to drive the shaft 26, the lever-arm 91. having guided movement on the base 10, is drawn outward, the said lever being connected at its inner end with the righthand peripheral portion of the wheel 88, as shown in Fig. 6, and by such an action the wheel is turned in direction of the right-hand side of the machine, and theconnecting-rods 87 and 89 are carried also to the right, restoring the lever St to its normal position and bringing the curved head 85 of the said lever again in engagement with its keeper 86.

A gong 92 is mounted on the cross-bar T4: of the carriage adjacent to the right-hand arm 69, as is shown in Fig. 6, and this gong is provided with a spring-controlled hammer 93, having an end which extends outward through the slot in the gong, and when the carriage is moved sufficiently to cause the aforesaid releasing action on the head of the lever 8% the projection from the hammer will strike a trip 94, extending from the rear edge of the upright 2et, which trip will cause the hammer to strike the gong and sound the alarm, as is I usual on type-writers, to indicate when the end of a line has been nearly reached.

.lVhen correcting the type-written matter, it is desirable that the plunger 81 shall be operated by hand, and to that end a spring-controlled button 95 is pivoted on the upper face of the cover-plate B, which button when it is pressed downward engages with the rear bar 78 of the cradle-section of the printing mechanism 1) and operates the said plunger 81 in similar manner to the pins on the shaft 26. The cover-plate B is held in position relative to the other plates by the cam-levers 4:1, heretofore described, and by the nut 53, which is screwed upon the upper threaded end of the stud 48.

It will be understood from the drawings and specification that should the powercontrolled shaft 26 be continuously operated the carriage will be actuated a letter-space to the right at regular intervals.

This type-writing machine is exceedingly simple in its construction, comprising but few parts, not liable to get out of order, and it is evident that it may be operated by any person capable of spelling properly.
